Barry Grant/Holley 750 Double Pumper Base Plate Question
Hey. Sorry I didn't see this earlier. There should be no connection between any fuel passages and the throttle shafts. If you see fuel there, it is not the throttle plate unless there was a porosity problem or crack.
Possible it is dripping from the boosters - that would suggest fuel level in the bowls is too high.
If not, look for other traces of where its coming from. Might just try a fresh set of good gaskets.
Hi,
thank you!
And this was the first thing I did - new gaskets and fuel Level.
After I changed a few gaskets (nearly everything) I did a short "off engine test".
I gave the carburetor fuel from a pressure free source and let the bowls fill.
I opened the throttle to see if the squirter nozzles are free and I noticed the fuel coming out of the accelerator pump is leaking at the throttle shaft.
I did the same procedure, after I installed the carb back again (fuel pressure 6,5-7 psi).
Same problem (with engine running)
So the Problem are the shaft bushings..... but as the whole base plate has seen better days, I want to replace it.
I am still searchin for the needed part, because I can't find a spare part # for the base plate....
And as I wrote above (and you can see or read) I live in Germany and we don't have much Shops for US-cars (and the ones, that exist have a criminal pricing strategy) :)
Anyway my Duster is in hibernation.... the carb has to be fixed till march
.... winter is coming and fortunately I have a DODGE RAM 1500 as daily drive.
Perhaps someone has a good onlineshop for me?
Regards, Eckhard :popcorn:
